SAN ANTONIO — A gas stove exploded at about 5:30 a.m. Wednesday in the 200 block of Lyman Drive in Terrell Hills, causing a fire that eventually engulfed the entire house in tall, thick flames.

A woman, whom neighbors said was in her 60s, lit the stove and began to walk away when it exploded, said Billy Knupp, chief of the Terrell Hills Fire Department. She was burned over 18 percent of her body, including possibly her face, but was conscious and alert and is expected to recover, Knupp said. Her husband was in the house but was not injured, authorities said. They were both taken to San Antonio Military Medical Center.

The explosion sent pieces of the house flying. A garage door landed in a yard across the street.

Firefighters spent at least an hour containing the fire and small flames were still burning two hours later. Crews from Terrell Hills, Alamo Heights, Olmos Park and Fort Sam Houston helped fight the blaze.
